there is a way to go around, but I am told that it is about 10 ms. & very sandy. There were goose berry bushes here by the road side, this was the first fruit we had seen; we gathered some of the green berries, stewed them for supper, found them delicious. We soon emerged into an open plain, where the main chain of the Rocky mountains appeared in the distance; Crossed Sweet Water again, went up a few miles & encamped; not very good grass, plenty of alkali, & some of the largest kind of sage, we soon had a good fire, for the nights are getting cool here in the mountains, & after supper we were seated around it, some sitting on yokes, & some on buffalo heads; & they do not make a bad seat; and some are used for writing upon, & then setting them up by the side of the road, generally informing the passerby, that Mr. A. B. &c. passed such a day, all well &c. Saw some written in '49 & '50, & though penciled was not yet effaced, we frequently find a buffalo head stuck up with a notice, that there is a spring in such & such a place; nearly all the skulls & shoulder blades along the road, are more or less written upon. Loyd he wrote a moralizing epitaph upon a very large old skull, stating that this animal had fulfilled the laws of nature, & that his head, still served as a seat to the weary traveler.

[June 24-72d day] Had a shower last evening, quite cool, have to wrap up to keep warm, good roads, except 3 or 4 this morning, passed the ice springs; here are great quantities of alkali, & saltpeter, which kills the stalk [stock] which stop here, for we saw more dead cattle to day, than we have seen before on the route. We did not stop to dig for ice,1 for we were cold enough without it. Passed on crossed Sweet Water twice, & encamped on the same, found tolerable grass. There was a trading post at the head of this little valey, which we passed in the morning. June 25-73d day] The roads to day hilly & rocky, weather cold, had a sprinkle of snow & hail; as we reached the top of a high ridge we had a fine view of the wind range of mountains 2 a little to our right, these are the highest peaks of these mountains, which we have been so long gradually ascending, nothing that I had before seen of mountain scenery, was half so beautiful, for the white snow lying upon the dark blue ground, looked like pictures of silver; no painting can give that delicate tint, of light & shade, & it continually varied, as the light of the sun shown upon it, or when it was obscured by clouds. We passed a bank of snow, and an ice spring, so called, from its water being as cold as ice could make it. It was excellent water but the weather was rather to cold to have made much of a relish for it. We went on to Strawberry creek & encamped, good grass, & the water of this beautiful stream, is excellent. George had a severe chill, this evening, and a high

fever, he was sick a day or two. We are about 15 ms from the South Pass, we are hardly half way.1 I felt tired & weary, O the luxury of a house, a house! I felt what some one expressed, who had traveled this long & tidious journey, that, "it tries the soul." I would have given all my interest in California, to have been seated around my own fireside, surrounded by friend & relation. That this journey is tiresome, no one will doubt, that it is perilous, the deaths of many testify, and the heart has a thousand missgivings, & the mind is tortured with anxiety, & often as I passed the fresh made graves, I have glanced at the side boards of the waggon, not knowing how soon it might serve as a coffin for some one of us; but thanks for the kind care of Providence we were favored more than some others.

[June 26-74th day] We proceeded onward, crossed Sweet Water for the last time, here it is a real mountain torrent, we soon arrived at the summit, or Pass of the Rocky Mountains, this has more the appearance of a plain, for it is some 5 ms across, & nearly 30 ms wide from north to south. The road is sandy, & some rocky, but not steep in no place here. We traveled about 25 ms to-day, & encamped below the Pacific Springs, poor place to camp, for where there is any grass, it is so miry that it is dangerous for stalk [stock] to go, 2 or 3 of ours got in the mire & a good many others, they were got out, but with much difficulty. We now consider ourselves about half way, but the "tug of war" is yet to come. We have now bid adieu to the waters, which make their way into the Atalantic, & now we drink of the waters which flow into the Pacific. Our faithful team still looks well, they, nor we, have not yet suffered only fatiegue, they have generally had plenty of grass & water, but according to the guides we may suffer for both, but hope to find it better than some have represented. More than half of the cattle on the road have the hollow horn, the man who is traveling with us has lost, several head & there are two or three more which will not go much farther.

MAKING A LINE ENGRAVING

FOLLOWING last year's exhibition illustrating the "Making of an

Etching," the Prints Division of The New York Public Library has now arranged one dealing with the "Making of a Line Engraving." (Print Gallery, room 321.) Here again the visitor is first taken through the various stages of the process. Copper plates are shown, bare and engraved upon, as also gravers, burnishers and other tools used by engravers; an original drawing and a gelatine transfer appear side by side with an impression from the engraved plate. The matter of states is illustrated notably by a series of thirteen progressive proofs of the engraving of a "Holy Family," after Raphael, by Lecomte. Pictures of engravers and printers at work round out this introductory survey of the process.

Then a series of prints, arranged in chronological order, show the development of the art from the earliest work to that of to-day, from the simplest treatment to the most varied and involved which can be produced with the graver. The short, scratchy strokes of early men, such as the Master E. S. of 1466, the free etching-like work of the Master of the Amsterdam Cabinet, these are developed into more regularity in the plates of Martin Schongauer. This regularity of line work finds its rich and logical development in Dürer. With Goltzius the method already becomes a matter of dazzling skill, a means that is sometimes an end in itself. And so the way is paved for ultimate decline into a dull regularity of line cutting. Similarly, in Italian engraving we find development - with a different national viewpoint and expression - from the early parallel uncrossed lines of shading (noticeable particularly in the work of Mantegna), through the dignity and reserve of Marc Antonio Raimondi, and the big gesture of Carracci, to the final sureness in execution attained by Morghen and his contemporaries in Italy, France and elsewhere. The brilliant craftsmanship of the French portrait engravers of the 17th century has its say here, too, and its echo in England is noted.

Then there is also a series of little groups showing development in certain directions: the French prints mirroring the gayety of the 18th century as shown in the works of its painters, book illustration in various countries, "annuals" (including "horrible examples") and "framing prints" in England and America, and bank-note work and its influence.

Here, then, as in the exhibition "The Making of an Etching," the principal object is to present to the visitor technical details illustrated in masterpieces of the art, the enjoyment of which is, of course, the end and object of the whole matter.
